Hedge fund manager Whitney Tilson was feeling happy Wednesday morning. After Donald Trump ridiculed Wall Street on the campaign trail, the President-elect tapped former Goldman Sachs Group executive Steven Mnuchin to be his Treasury secretary and billionaire investor Wilbur Ross to lead the Commerce Department. Trump even met with Goldman Sachs President Gary Cohn inside Trump Tower. It would suit Tilson just fine if voters who backed Trump because he promised to rein in Wall Street are furious now that he's surrounding himself with bankers and billionaires. "I can take glee in that -- I think Donald Trump conned them," said Tilson, who runs Kase Capital Management. "I worried that he was going to do crazy things that would blow the system up. So the fact that he's appointing people from within the system is a good thing."
